The National Security Adviser’s office has requested former Kaduna Governor, Nasir El-Rufai, to provide proof of his assertion that the agency acquired a lethal chemical called thallium sulphate.
Sources confirmed that the request came after El-Rufai sent a letter to National Security Adviser Nuhu Ribadu on January 30, 2026, in which he claimed that approximately 10 kilograms of thallium sulphate was obtained from a supplier in Poland.
Thallium sulphate is a highly toxic, colorless, and odorless substance that can be deadly even in small amounts.
In a response dated February 13, 2026, and signed by Brigadier General OM Adesuyi on behalf of the NSA, the office rejected El-Rufai’s allegations.
The letter stated that the Office of the National Security Adviser neither acquired nor initiated any plans to purchase the chemical and had no intention of doing so.

The statement also mentioned that the allegations have been forwarded to the Department of State Services for a comprehensive investigation.
It indicated that El-Rufai and anyone else with pertinent information would be invited to provide evidence to clarify the situation.
It has been reported that in an earlier attempt to deliver the response letter to El-Rufai’s residence in Abuja failed when security personnel reportedly refused to accept it.
The letter was eventually delivered on Sunday and signed for by the head of security on El-Rufai’s behalf.
Last Friday, during an appearance on Arise Television, El-Rufai claimed to have listened to an intercepted phone call allegedly involving Ribadu. He stated that someone had tapped the NSA’s phone and that he heard Ribadu instructing security forces to arrest him.
This situation has heightened the public confrontation between the former Kaduna governor and the national security authorities.
